LOOK-SHUTTLE Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed June 15, 1908. Serial No. 438,455.

To all whom it may concern:

Be it known that I, Josnrn H. Moron, a citizen of the United States,residing at Millbury, in the county of Worcester and State ofMassachusetts, have invented certain new a'id useful Improvements inLoom-Shuttles, of which the following is a specification.

My invention relates to loom shuttles, and particularly to a loomshuttle of the class shown and described in U. S. Letters Patent,

No. 302,922, in which there is a spring nctuated pin connected with thecatch or locking device for the hood of which pin, on the raising of thespindle, engages with the body of the shuttle and is forced outwardly,against the action of the spring, to release the locking device.

The object of my invention is to improve )on the construction of loomshuttles of the ass referred to.

In my improvements 1 rovido a metal device, preferably of sta ile shape,with an offset head, which device is entirely independent of thespindle, and is combincd with the body of the shuttle by inserting thelegs or extensions of the device into holes extending in the shuttlebody, one on ouch side of thespindle head, and directly in front of thepivot pin of thespindle, so that the olfsr-t heat of the device Wlllextend in the path of and form an abutment or engaging surface for thehead of the spring actuated pin of the bobbin catch, when the spindle israised, and the two legs or extensions on the device will extend infront of the pivot pin for the s indle hcad,-one leg or extension oneach side of the spindle head and extending into the sides of theshuttle to bind together the sides of the shuttle body. It is found inpractice, that the transverse pivot .pin for the spindle head in theshuttle, will, in the constant use of the shuttle, by reason of itsengagement with the ickcr on the opposite end of the loom from t e headof the shuttle, wear the transverse opening through the shuttle body,and cause the. pin to work loose. In my improved abutment device for thehead of the s ring actuated pin of the bobbin catch, by cving one orboth of the legs or extensions on the device, located directly in frontof and'in the path of the pivot pin of the spindle, I provide a bearingor abutmentsurface for said pin,;in case in the constant use of theshuttle, said pin has enlarged the transverse opening, and prevent anyfurther enlargement of said opening for bobbin on the spindle, the

the pin, all as will be hereinafter fully dcscribed.

My invention consists in certain novcl features of construction of myimprovements as will he hereinafter fully described.

Referring to the drauiugzlfigure 1 is s. top or plan View of one end ofn shuttle run-- bodying my in'iprovemcnts. Fig. 2 is n side View of theend of the shuttle shown in Pig. 1, looking in the direction of arrow11, same figure, with portion of the body of the shuttle broken away.Fig. 3 is a central longitudinal :scction, on line 3, 3, Fig. 1, lookingin the direction of :n'row (1, sumo figure, and showing the spindle inits raised position. Fig. 4 is :1 side perspective view of my abutmentdevice, detached.

In the acronnmnying drawing, 1 is n portion of the body of n. loomshuttle, uhich is recessed through its central portionin the usual way,to receive the spindle 2. The spindle 2 has :1. head 2', with atransverse opening lhercthrough for the pivot pin 3, which extendstransversely through the body of the s'nttle. in the usual way. Tho-howl.3 of the spindle 2, has a pin 4 extending through on opening therein,with a. lock or catch 5 for the bobbin, attached fhcrcto. A hclicollycoiled expansion spring 6 extcnds within an opening in the head 3 of thespindle L, and engages with one end the heard 4 of the pin 4, and withits other end the lower end of the o cniru 2" in the head 2 of thespindle 2, sec %ig. 3.

ithin on opening 1 in the body of the shuttle l, is located a. pin orstud 7, having a. hclirnlly coiled expansion spring! 8 encircling thesome. The head T on the pin 7 is adapted to cngngc the heel 13"" on thespindle .2, to hold the spindle in its closed and open osition.

All of t e above parts may be of the usual and ordinary construction inthe class of loom shuttles referred to.

I will now describe my improvements.

I provide a device 9, preferably made of wire, and preferably of theshape shown in Fig. 4, that is of staple or open end loop shape, havingthe curved top or head 9', and pre erably two downwardly extending endsor legs 9. The device 9 forms the abutment or engaging surface for thehead 4 of the pin 4, which is connected with the looking device 5. Theabutment device 9 is combined with the body 1 of the shuttle, preferablyby boring in the shuttle body cutting away the body of the shuttle onthe upper side thereof, above the pivot pin 3 of the spindle 2.

The abutment device 9 has its legs or ends 9" inserted into the holes1in the shuttle body 1, and said device is forced or driven down untilthecurved shaded top J of the device -9 extends with n tie upper surfaceof the shuttle body 1, and in the path of the head 4 of the pin l, whenthc spindle 1 is raised, as shown in Fig. 3. The two extended ends orlegs 9 will extend directly in front of, and in the path of the pivotpin 3, see Fig. 2.

The advantages of my improvements will be readily appreciated by thoseskilled in the art.

The abutment device 9 is entirely independent of the head of thespindle, and of the ivot pin 3 therefor, and disconncctml thererom, andby its location in the shuttle body,

with one of its downwardly extending: cnds 9" on each side of thespindle head 2, it acts to bind together the sides of the shuttle body,and hold them in position at the spindle head. The downwardly cxtcndin;ends 9 of the device 9, extending in front of the pivot pin 3 of thespindle, act to form a earing surface for the pivot pin 25 to strike 3 rto, of a metal abutment device to be engaged against, in case, in theuse of the shuttle. said in wears the transvcisc hole in the shutt ebody, as is ordimn'ily the case.

It will be understood that the details of construction of myimprovements in an abutment device for the )ring' actuated pin of thebobbin catch or loc mechanism may be varied if desired, and it isadapted to be combined. with shuttles of any usual and Well knownconstruction.

I prefer to have the extended cnds or logs 9 on the spindle 9 of uniformlength, but this is not essential, and one leg may be shorter than theother, and only one of the legs ma extend below the pivot pin I), thoughprefer to have hot h legs cxtcnd below the pivot pin.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. in a loom shuttle of the class described, the combination with thebody of the shuttle at the spindle head end, of a metal device orstaple, raving an offset head. extending in the path of and adapted toform an abutment for the spring actuated pin of the bobbin catch orlock, when the spindle is raised, and having its two ends extend inholes in the shuttle body on each side of thespindle head, anddisconnected therefrom, and in front of and in the path of the pivot pinof the spindle, to form a bearing surface for said pin to engage, incase said in Wears the transverse hole in tlnyshnttlc iody.

2. In a loom shuttle of the class described, the combination with thebody of the shuttle at the spindle head end, of a metal device or staplehaving an offset head extending in the path of and adaptedto form anabutment for the s n-ing actuated pin of the bobbin catch or lOC k, whenthe spindle is raised, and having one or both ends extend in holes 'nthe shuttle body on each side of the spindle head and disconnectedtherefrom, and in front of and in the path of the ivot pin of thespindle, to form a hearing set are for said pin to engage, in case saidpin wears the transverse hole in the shuttle body.

il. in a loom shuttle, the combination with the spindle pivoted at oneend, and a spring: actuated pm in the spindle head hav ing the bohhincatch or lock attached thereby said. spring actuated pin, when thespindle is raised, and to extend in front of and in the path ol thepivot pin of the spindle head, said device having); an o'llset headforming the ahutincnt for the spring actuated pin, and one or two endsor legs which extend in holes in the shuttle body on each side of thespindlc llt'illl, on the inner Side Of the pivot pin of the spindle, anddisconnectcd from said pivot \in, and forming an (Ilf,:l.ll1 surface forsair pin in case said pin n-ca rs lhc transrcrsc hole 111 the shuttlebody.
